Researchers unveil multi-mode reactions in perovskite solar cells

As a promising photovoltaic material, metal halide perovskite yields high efficiency in solar cells. However, the deep-level traps of minority carriers at the surface of the p-i-n perovskite solar cells can suppress nonradiative recombination. The precise passivation of deep-level traps has been a major focus in raising the power conversion efficiency (PCE) to the theoretical Shockley-Queisser limit.
